131 Chapter 12 Network Address Translation (NAT) Screens
Note: Port numbers do not change for One-to-One and Many One-to-One NAT
mapping types.
The following table summarizes these types.
12.2 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two
types of mapping, Many-to-One and Server. The Prestige also supports Full Feature NAT to
map multiple global IP addresses to multiple private LAN IP addresses of clients or servers
using mapping types. Select either SUA Only or Full Feature in the WAN IP screen.
Note: Choose SUA Only if you have just one public WAN IP address for your
Prestige.
Note: Choose Full Feature if you have multiple public WAN IP addresses for your
Prestige.
12.3 SUA Server
A SUA server set is a list of inside (behind NAT on the LAN) servers, for example, web or
FTP, that you can make visible to the outside world even though SUA makes your whole
inside network appear as a single computer to the outside world.
